Got a new kit for you - the K SMD L293D Motor Driver. No, no, the SMD isn't "surface mount" - it's the Secret Motor Driver! This L293D-based motor driver fits secretly inside most standard servo cases like the Futaba S3003/S148, and our own GM4 gear motors. It replaces the low-voltage original electronics with LED-indicated, […]

GM15 Nano Robot Sumo
We've had some requests about our own demo Nano robot sumo "BittyBad", which uses a pair of GM15 gear motors. On the GM15 detail page, you'll see a picture of it! It features 2 GM15 gear motors, two 90mA/h LiPoly 3.7V batteries (in series), two "ProxDots" objects sensors, a pair of edge-sensors and a (gasp!) […]
